Abstract

A wireless earphone may include a first group of contact electrodes, an earphone module, a power module, and a control module. The contact electrodes contact a second group of contact electrodes of a charger to establish an electrical connection between the wireless earphone and the charger. The earphone module outputs a sound signal. The power module provides operating power to the earphone module. The power module is charged from the charger via the first group of contact electrodes. The control module is configured to: in response to establishment of the electrical connection between the wireless earphone and the charger, perform control to prohibit charging the power module using charging power from the charger within a first time period; and after expiration of the first time period, perform control to allow charging the power module using the charging power from the charger.
